Evaluate the function at the indicated values. (if an answer is undefined, enter undefined.) f(x) = 8x + 9 f(1) = f(−2) = f 1 2 = f(a) = f(−a) = f(a + b) =

f(1)=17

f(-2)=-7

Step-by-step explanation:

We are given that a function

We have to evaluate f(1),f(-2) and

Substitute x=1 in the given function  then we get

f(1)=17

Substitute x=-2 in the given function then we get

f(-2)=-7

Substitute

Then we get

c

step-by-step explanation:

h * s * a

h = history teacher

s = science teacher

a =   art teacher.

i see no data table, but just multiply the number of history teachers, science teachers, and art teachers.
